' The' present invention relates 'generallyto hay presses andparticularly tothe tuckers therefor," such'v tucking devices being com-'monly provided on kbaling presses? for tucking ends of the hay betweensuccessivev charges; Y

As Vis well Vknown by those familiar.withA these machines, theytuckerrmust be mounted Vso that itl ican yield under the pressure'of thehay passing under it, rparticularly when *a relatively heavy chargeofnhayisforced below the tucker. One ofthe principal objects oftheinvention is to provide-anlmproved Y tucker mounting; which will permitthe tuckerV to' swing upwardly with a rocking movement as well asto liftsubstantially vertically', the

y combination of these two `movements aifording an amplitude ofmovementof the tucker sufficient to accommodate even theheaviest overcharge ofhay'. p In the preferred construction, a'rollerftype vof tucker isused',` and in'y suchembodiment the tuclerV is capable ofthree'movements in the act o'ftucking inthe hayandad'apting litself tocharges of different sizes, thesethree movements consisting ofrotationof the roller Y on its own axis, upwardswinging or-rocking roller.

Ofany conventional type of ha-y press, shownfor the purposes ofillustrating a typical adaptation, it being understood that thepresenttucker is adaptable to practically any type of press.

This tucker, indicated in entirety'at 25,`

is mounted on the top ofthe frame or bale chamber 7 just at or inproximity to the end of the-feed opening through which the hay is-forcedfrom the hopper 23 into the bale chamber. Thev tucker comprises a roller26 Vmounted on a transversely extending shaft 27, the ends of the rollerbeing'closed by drums or heads 28 which are pinned or otherwise securedtherein and which have relatively long bearing hubs affording extensivebearing support for the roller 26 on the shaft 27. Any suitablemechanism may be employed for preventing rotation of the roller in wonedirection, the present mounting' of the tucker being adapted, however,to that type of mechanism which is completely enclosedV within theroller.. In such construction, a hub or boss 29 is fixedly secured onthe shaftA 27, preferably midway between the ends of the roller, suchhub or boss-having llaterally extending portions for receivingtransverse pins passing through the shaft 27 and non-rotatably securingthe member 29 to the shaft. As shewnrin Figure 4, the circular peripheryof said member 29 is spaced slightly from theinner wall of the cylinder26 to avoid frictional wear between the parts, and Iformed in theperipheralportions of said member are a plurality oftapering pockets 31.There are preferably two of these pockets located substantially at thepoints shown,

v each pocket being of increasing radial depth in a directioncorresponding to the direction offree rotativemovement of the roller 26.

Disposed in these pockets are clutch elements 32 which are free to rollfrom end to end of the pocket, such elements consisting either ofballsor of cylindrical rollers, either type being optionally employed. Eachpoclret 31 has sidev walls 33 which prevent endwise displacement of therollers or balls from the stationaryclutch member 29. The arrow m inFigure l indicates the direction of A free'rotative movement of thetuclrer roller 26, and it will be observed that the two pockets 3l 'aresoy arranged that gravitational force acting on the clutch elements 32will tend to roll these clutch elements downwardy ly toward the shallowends of the pockets, in

a direction counter to the direction ofv free rotative movement of thetucker roller. R0- tation of the tucker roller in the directionindicated will merely result in the clutch elements 32 playing idlybetween the inner surface of the roller and the lower ends of thepockets 31. When, however, the tucker roller starts to revolve in theopposite direction the clutch elements will be forced into wedgingengagement between the inner surface of the-rollerand the shallow endsofthe pocxets 31, thus holding the roller against such rotation by thefrictional or wedging pressure which the clutch elements establishbetween the roller and the stationary clutch member 29.r rlhe use ofsuch type of ball or roller clutch, enclos-ed completely lwithin thetuck- Aends of these arms arecurved circularly and are ofapproximately'the samediameter as the tuclrer roller, whereb-ythey formin effect end continuations of said .roller and close lthe spacesbetween the ends of the roller and the side walls of the bale case. Theroller shaft 27 has its ends projecting beyond the ends of the rollerand rigidly secured within the side arms 35 sothat said shaft is heldagainst axial rotation. The upper ends of these depending side arms 35are formed with horizontal hubs or bosses 36 which are secured to atransversely extending rock shaft 37 disposed above the tuclier roller.To more effectively secure. the hubs 36 to said shaft the lat- `Figure3, these side walls are provided with Vslotted openings 39'havingrounded lower ends in which 'the rounded under surface of the shaft hasrocking support. Extending downwardly from the ends of the rock shaft,outside of the bale case, are'arms 41 which may be formed as downwardlybent extensions of-saidl shaft or which may consist of separate armsrigidly secured to the shaft. Said arms` extend down a suflicientdistance from'the shaft to have considerable leverage thereon, and areapertured at their lower er, in the forward compressingV stroke ofthe'plunger l5 the Atucker roller 26 will revolve freely as the'hay isvforced. under the same, theV ball lclutchl mechanism: permitting 1rotation 'bottom of the bale case;

Referring lnow to the operation of the tuckof therol'lery in this.direction, Concurrently lwith the rotationof the rollerit ispressed"yieldingly downwardlyagainst the top' ofthe i charge of hay under theaction of theisp-rings VIn maintaining this pressure engagement theroller is capa-ble of yielding in two directions or with 'two motions,towit: The roller can swing forwardly and upwardly around the axisof therock shaft 37 with' the forward movement of the'charge' of hay, and theroller can also be displaced substantially.vertically-- With atranslat0rymotion-- Thus the roller is capable of accon'imodating-itselfeven tofan excessive overcharge of hay', thecombinatio-n of the swingingand translatory movements affording a. wide rangeaoff. movement of theroller. `It will be noted that the springs 42 yieldingly resist bothmovements. When the roller oscillates forwardly and upward-ly around theaxis of the rock shaft 37 the side arms 4l function asl crank armskthrough 'which the springs 42 transmit their tension fto oppose suchrocking movement of the shaft 37 Similarly, when'the -roller is dis-vplaced upwardly in its translatory movement the springs 42also'yieldingly oppose such'` motion, tending to hold the rock shaftdownin the'lower ends of the slots 39;' By adjusting thetension of thesprings42 the pressure which the j roller exerts against the charge' ofhay can be increased or decreased. Inthefretractive movement of theplunger 15 the roller m'oves' down behindthe com-Y pressed charge of hayunder the 'action lof such springs, thus turning'- downwardly or tuckingin the ends of the Vhay projecting from the upper part of thisjcharge.`In such l-retractive movement of the plunger, the ball clutch mechanismcomes into operation for holding the roller against rotation in theopposite direction, which aids in-tncking in the projecting endsoffthehay andpreventing such from being-drawn backwardly by theretractive movement of the plunger.l

In the next forward stroke` of the plunger the tucked-ini ends will -becompressedA between the previouscharge and the new charge being forcedforwardly by the plunger.
